This is a cisco ASA 5505, I did a password recovery, got in and configure config register 0x00000041, write mem, reboot and after rebooting the firewall went into ROMMON over and over.
These are the steps I took:
1.- From ROMMON re-installing the asa version 7.2.3 using tftp server and the image was successfully installed. I was able to log in and run boot system flash:asa723.bin, write mem, reboot and the firewall which continue rebooting and rebooting until I click on Escape key then I went back to ROMMON.
2.- I went through the tftp process, change the config register 0x1, write mem, reboot and continue rebooting and rebooting until I click on Escape key then went back to ROMMON.
3.- I went through the process of running the rommon1>confreg process and when I configure boot, the firewall went into rebooting and rebooting again.
I notice that when I run the tftp process, connected all the way to ciscoasa# and run sh version: it says that: system boot is tftp://192.168.1.10
. I have checked all the possible ways.
